(57) A silver halide color reversal photographic photosensitive material is disclosed
comprising a support having thereon at least one red sensitive emulsion layer, at
least one green sensitive emulsion layer and at least one blue sensitive emulsion
layer, at least one hydrophilic colloid layer of said photographic photosensitive
material containing a microcrystalline dispersion of at least one compound selected
from the compounds represented by formulae (I), (II), (III), (IV), (V) and (VI), and
at least one hydrophilic colloid layer of said photographic photosensitive material
containing at least one compound represented by formula (VII):
wherein A and A′, which may be the same or different, each represents an acidic nucleus;
B represents a basic nucleus; and X and Y, which may be the same or different, each
represents an electron attractive group; R represents a hydrogen atom or an alkyl
group; R₁ and R₂ each represent an alkyl group, an aryl group, an acyl group or a
sulfonyl group, or R₁ and R₂ are joined together to form a five or six membered ring;
R₃ and R₆ each represent a hydrogen atom, a hydroxy group, a carboxyl group, an alkyl
group, an alkoxy group or a halogen atom; R₄ and R₅ each represent a hydrogen atom
or a group of non-metal atoms joined together with R₁ and R₂, respectively, to form
a five or six membered ring; L₁, L₂ and L₃ each represent a methine group; m represents
0 or l, n and q each represent 0, 1 or 2, and p represents 0 or 1, and when p is 0,
R₃ represents a hydroxy group or a carboxyl group and R₄ and R₅ each represent a hydrogen
atom; B′ represents a heterocyclic group containing a carboxyl group, a sulfamoyl
group or a sulfonamido group;
said compound represented by formulae (I) to (VI) containing at least one dissociable
group such taht the pKa value of the compound in a 1 : 1 by volume mixed solvent comprising
water and ethanol is within the range of from 4 to 11:
A-(Time)t-Z (VII)
wherein A represents a redox parent nucleus which eliminate -(Time)t-Z by oxidation during photographic development processing; Time represents a timing
group which is bonded to A with a sulfur atom, a nitrogen atom, an oxygen atom or
a selenium atom; t represents an integer of value 0 or 1; and Z represents a development
inhibitor group.
